By using various expansions of the parametric digamma function and the methodof residue computations, we study three variants of the linear Euler sums,related Hoffman's double $t$-values and Kaneko-Tsumura's double $T$-values, andestablish several symmetric extensions of the Kaneko-Tsumura conjecture. Somespecial cases are discussed in detail to determine the coefficients of involvedmathematical constants in the evaluations. In particular, it can be found thatseveral general convolution identities on the classical Bernoulli numbers andGenocchi numbers are required in this study, and they are verified by thederivative polynomials of hyperbolic tangent.
